Dynapack Hub Dyno — Accurate Power Measurement in Castleford
No tyre slip. No guesswork. Just accurate, repeatable power and torque figures — bolted directly to your hubs.
THE TECHNOLOGY
What is a Hub Dyno and Why is it Better?
Most dynos you'll find are rolling roads — your car sits on large rollers and the tyres spin against them while the machine measures resistance. The problem? Tyre slip, tyre pressure, tyre temperature, and even tyre compound all affect the number you see on the screen. Run the same car twice and you can get noticeably different results.
Our Dynapack hub dyno works differently. We remove your wheels and bolt the dyno pods directly to your wheel hubs. The measurement happens at the hub — no tyres in the equation at all. The result is significantly more accurate and repeatable figures, which is exactly what you need when tuning or diagnosing a car.
It's also safer. Because your car is physically bolted to the machine, there's zero risk of it coming off the rollers — something that can happen on a traditional rolling road, especially with high-power vehicles.
| Rolling Road | Dynapack Hub Dyno | |
|---|---|---|
| Tyre slip | Yes — tyres spin on rollers | None — bolted directly to hubs |
| Repeatability | Varies between runs | Highly repeatable results |
| Safety | Car can come off the rollers | Car is physically bolted in place |
| Affected by tyre pressure | Yes — changes readings | No — tyres not involved |
| Affected by tyre temperature | Yes — changes grip on rollers | No — tyres not involved |
| Suitable for high-power cars | Risk of tyre slip at high power | High upper limit — rated to 3,500 Nm |
